POWER-SLEDGE.

Specification of Letters Patent.

Patented J an. 9, 1906.

Application filed November 30, 1904. Serial No, 234,922.

Be it known that I, FRITZ CHARLES Mons, a citizenof the United States, residing at Elwood, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Power-Sledges, of which the following isa specication.

In the manufacture of black, terne, or tin plate the black sheets are rolled and doubled and again rolled and after being trimmed are separated, pickled, and stacked in annealingpans and annealed. When they are cooled, these stacks are carried to cold rolls and there subjected singly to the rolls. As a result of the previous treatment the sheets stick together, and in order to loosen them one from the other it has been customary heretofore to beat the top of the stack with hand-sledges, this operation requiring the services of two men and being re eated many times before 'all of the sheets o the stack have been separated. This operation is exceedingly expensive and time-consuming, and it isnecessary practically to keep two laborers busy on each two sets of rolls The object of my invention is to produce a machine which shall be capable of sledging the stacks of sheets for a large number of rolls, the operation being rapid, uniform, and entirely under control of the single operator.

The accompanying drawings illustrate my ginvention.

Figure 1 is a side elevation Fig. 2, a front elevation g Fig. 3, a plan, and Fig. 4 a detail.

In the drawings, 10 10 indicate a pair of bars each of which is supported upon a suitable track 11 by a pair of wheels 12. Rising are upright frames 13, and these uprights are connected at their upper ends by a suitable top frame 14. Journaled in suitable bearings in the carriage thus formed are four vertical screw-rods 15, each of which passes through a nut 16, (see dotted lines, Fig. 1,) carried by a vertically-adjustable cross-head frame 17, this construction being similar to that commonly-employed in many machine-tools and of such character that by simultaneous turning of the four screw-rods 15 the cross-head frame 17 may be vertically adjusted. In order to accomplish the simultaneous movement of thescreW-rods 15 in either direction, each of said screw-rods is provided at its upper end with a sprocket-wheel 18, and a suitable sprocket-chain 19 is passed around all four of the sprockets 18. One of the screwrods 15 is provided on its upper end with a bevel-gear 20, which meshes with a gear 21, carried by a counter-shaft 21, j ournaled in suitable bearings on the cross-frame 14, J ournaled on the shaft 21 are two bevelgears 22 22, which mesh with a suitable driving-gear 23, j ournaled on the frame 14. Arranged between the two gears 22 is any suitable form of shiftable clutch 24, which may be shifted into engagement with either of said gears by means of a suitable shifting-lever 25. Lever 25 is provided at its outer end with a slot 26, into which extends the cranked end 27 of the vertical rock-shaft 28. Shaft 28 is extended downwardly in suitable bearings on` one of the sides 13 to a point within easy reach ofthe operator and there provided with a pivoted hand-lever 29, which is adapted to enter any one of a series of notches in the segment 30, the arrangement being such that by rocking shaft 28 the movement of the screw-rods 15 may be controlled.

The gear 23 is a combined beveland spur gear, and the spur portion meshes with one of a train of gears 31, the final gear of the train beingcarried by a vertical shaft 32, j ournaled in suitable bearings on the frame. This shaft carries near its lower end a bevelgear 33, which meshes with a bevel-pinion 34, carried by the shaft of an electric motor 35, mounted on one of the side bars 10.

Splined upon shaft 32 and vertically movable thereon is a beveled pinion 40. This pinion 40 is journaled in a suitable bracket 41, carried by the cross-head 17, so as to partake of the vertical movement of said crosshead, and the pinion meshes with a beveled gear 42, carried by a hammer-shaft 43, which is ournaled in suitable bearings on the crosshead 17. Splined upon shaft 43 is'an eccentric 44, upon which is mounted an eccentricstrap 45. This strap carries at its lower end a bow-spring 46, to which is attached a vertically-reciprocable hammer-head 47. The

hammer-head is supported in suitable guides 48 of a carriage 49, and the carriage is provided with suitable rollers 50, which rest upon the cross-head 17, and thus permit reciprocation of the carriage 49 along the cross- The eccenhead parallel with the shaft 43.

IOO

tric 44 is, as previously stated, splinedupon shaft 43 and is mounted between sultable portions of the carriage 49, so as to partake of the longitudinal movement of'said carriage. The farther end of the shaft 43 carries a Worm 51, which meshes with a worin-wheel 52, carried by a shaft 53, journaled in suitable bearings on the cross-head 17 at right angles to the shaft 43. The shaft 53 carries a crank-arm 54, provided with a slot 55. Mounted in this slot is a wrist-pin block 56, which may be clamped in any desired position in the slot by means of a hand-wheel 57 and screw 58. Pivoted to the wrist-pin block 56 is one end of a pitman 60, Athe opposite end of which is pivoted to the carriage 49, the arrangement being such that rotation of the shaft 53 produces reciprocation of the carriage 49 on the cross-head 17.

In order that reciprocation of the carriage 49 may be under control of the operator, the Worm-wheel 52 is connected with the shaft 53 by means of a suitable clutch 61 of any desired form. (Shown in dotted lines in Fig. 3.) The clutch 61 is under control of a lever 62, which lever is connected, by means of a link 63, with an arm 64, splined upon a rock-shaft 65, journaled in suitable bearings on one of the upright frames 13. Attached to the lower end of the rock-shaft 65 is an arm 66, to Which is attached one end of a link 67, the opposite end of said link being pivoted to the lower end of a hand-lever 68, pivoted at 69 to the adjacent side bar 10. The upper end of the lever 68 is extended up to within convenient reach of the operator, who will stand upon a platform 70, secured to the adjacent side bar 10.

The machine thus described maybe shifted on its track by hand, if desired; but I prefer that it be self-propelled in order that the operator may readily bring the hammer into action at any desired portion of the upper end of the stackof lates 75. Forthispurposeoneend of the sha t of the motor 35 is provided with a gear 80, which meshes with a combined spur and bevel gear 81. Thebeveled portion of the gear 81 meshes with a pair of bevel-gears 82, which are j ournaled upon a counter-shaft 83. Splined upon the counter-shaft is a clutch lnember 84, which lies between the two gears 82 and which may be shifted, by means of a yoke 85, into engagement with either of the gears 82. The yoke 85 is carried by a rockshaft 86, mounted in suitable bearings on one of the side frames 10 and extended rearward beneath the platform 70. Shaft 86 is provided at its rear end with a lever 87, which is extended up to within a convenient reach of the operator. The counter-shaft 83 carries a sprocket-wheel 88, connected by a chain 89 with a sprocket-wheel 90, carried by ya counter-shaft 91, journaled in suitable bearings on the adjacent side frame 10. This countershaft carries a second sprocket wheel 92,

which is connected by a chain 93 with a sprocket-wheel 94, carried by a counter-shaft 95, which extends across the gap between the two upright frames 13 and is provided at its ends with sprocket-wheels 96, connected by chains 97 with sprocket-wheels 98, each attached to the shaft of one of the carryingwheels 12, one upon each side of the machine. Secured to the machine is a suitable trolley 100, which carries wheels adapted to engage the supply-wires 101.

In operation the tracks 11 are laid parallel to several sets of rolls, straddling the position ordinarily occupied by the annealing-pans 75. The stacks of sheets 75 are brought to their usual positions in front of the rolls, and when the sheets of any stack stick to such an extent that the operators cannot readily separate them the operator of my improved power-Sledge by manipulation of the lever 87 runs the machine to a point Where the hammer-head 47 lies above the stack. By manipulation of the hand-lever 29 the operator is then able to adjust the cross-head 17 vertically, so as to bring the Ahammer-head to a proper height, so that when reciprocated it will deliver any desired force of blow to the top of the sheet-stack. By manipulation of the hand-lever 68 the crank-arm 54 is rotated about shaft 53, and the carriage 49 is thus reciprocated on the cross-head 17, thus causing the hammer to deliver blows in a line across the top of the sheet-stack. By manipulating the several levers already described the operator is enabled to cause the hammer-head 47 to strike any desired point in the top of the stack, and as the force of the blow can be readily regulated only suf- IOO ficient hammering is produced to accomplish the desired loosening of the sheets. The blows may be struck very rapidly, so that the hammering on the top sheet may be very uniform and yet avoid any such permanent denting of several sheets. When the sheets at the top of the stack have been loosened, the machine is run to another stack opposite another set of rolls.

I claim as my invention- 1. In a power-sledge, the combination with a portable carriage, of a cross-head carried thereby, a plurality of threaded vertical shafts journaled on the portable carriage and engaging said cross-head, intermediate connections between said several threaded shafts for causing simultaneous movement thereof, a reciprocating hammer carriage mounted on the cross-head, means for reciprocating said hammer-carriage on the cross-head, a vertically-reciprocable hammer mounted on the hammer-carriage, and means for reciprocating said hammer.

2. In a power sledge, the combination with a portable carriage, of a cross-head carried by said carriage and vertically adjustable thereon, a hammer-carriagemounted on IIO ITS

said cross-head and horizontally reciprocable thereon, a hammer carried by the hammercarriage and vertically reciprocable thereon, a motor mounted on the portable carriage, and intermediate independently-controllable connections between said motor and the ham'- mer-carriage and hammer whereby the hammer-carriage and hammer may be independently or simultaneously reciprocated.

3. In a power Sledge, the combination with a portable carriage, of a cross-head carried thereby, means for vertically adjusting said cross head on the carriage, a hammercarriage horizontally reciprocable on said cross-head, a horizontal shaft journaled on the cross-head, a splined driving connection between said shaft and the hammer whereby said hammer may be vertically reciprocated by rotation of the shaft, a crank-and-pitman driving connection for the hammer-carriage, means for varying the effective length of the crank thereof, a motor, and intermediate independently-controllable driving connections between said motor and said shaft and said crank, substantially as and for the purpose set forth.`
